To all whom t may concern:

Be it known that l, REUBEN C. LrNnsrEN, a citizen ofthe United States, residing at following is a specification.

be freely used without danger of reaking,

This inventioirrelates to grain drills, and

it has for its object to produce a grain drill which will be adapted for corn field work as well as for open field work; that is to,say, a di lwhichl while capable of being successftifrlly used for open eld work will'be especially adapted for use in corn fields where, owing to its peculiar construction, it may down or injuring the stalks of the growing corn.

A further object of theinvention is to produce a grain drill capable of straddling a row of corn and equipped with presser wheels to press and compact the soil over the seed that is being dri led.

` A further object of the invention is to produce a corn field drill of the class described 'which may be drawn by four horses hitched vabreast with an equalized draft.

further object of the invention is to produce a simple and improved construction whereby the drills may be moved together or apart at the will of the operator during the operation of the achine, the construction being, moreover, .zof such a nature that the draft will always be on center.

A further object of the invention is to simplify and improve the mounting and arrangement of the furrow opening disks.

Further objects of the invention are to simplify and improve the general construc tion.l arrangement and operation of the parts of ,the improved machine.

lWith these and other ends in view which will readilv appear as the nature of the invention is better understood, the same. consists in the improved construction and novel arrangement and combination of parts lwhich will be hereinafter fully described and particularly pointed out in the claims.

In the construction of the improved machine, it will be understood that it may be made of dimensions to operate in the interspaces between-three or more rows of corn. For practical purposes it is thought, however, that a machine comprising two drill gangs and adapted .to work in the interspaces between three rows ofcorn will be most practicable, and such a machine has enlarged,

enlarged,

accordingly been illustrated. Assuming that the corn rows are three feet six inches apart, the main top frame bars, front and, rear, designated, respectively, by 20 and 21, must be ten feet six inches in length, so as to eX- tend entirely across three rows of corn and` midway into the adjacent interspaces. Said p wheat, between the rows of corn after the latter has attained a stage of growth that will not permit an ordinary drill to be used.

The top frame bars, front and rear, are connected together midway between their ends by a longitudinal frame bar 22.

-Similar longitudinal bars 23 connect the front and rear bars 20, 21 together some distance from the ends thereof, said bars 23 being spaced from the center a distance of three feet six inches to be equal to the distance between the corn rows, the object being that the center bar 22 and the side bars 23 shall precisely aline with the rows of Acorn. Connectingmembers, such as plates 24, of cast iron, or other material, serve to connect the center bar 22 and the side bars 23 with the front and rear bars 20, 21, the parts being assembled by means of bolts or the like; braces 25 have also been shown at the corners of the frame structure. It may here'be noted that in the construction of the entire frame of the machine, tubular metallic bars of rectangular cross section have been indicated wherever practicable, it being, however, understood that no limitation is intended to the use of any particular material.

Connected with the front top bar 20 and extending downwardly from the ends-'thereof are brackets or arms 26 whichare reinforced by inclined braces 27 extending from the lower ends thereof to the bar 20 with which said braces are connected at a suitable distance from the ends thereof; The

lower ends of the brackets 26 are also conf nected by inclined longitudinal braces 28 with the rear top bar 21, thus strongly reinforcing the brackets 26 which, as will presently hereinafter appear, are utilized as draft members. Connected with the front top bar 2O are also two yokes A each comprising two downwardly convergent side bars 29 and a bridge member or cross bar 30 connected with and supported said side bars. The yokes A are placed equidistant from the center of the top bar 20, and the lower ends of theside members 29 of ther respective yokesare connected with lll "it l the top bar v20 by obliquely disposed braces 31, whereby the parts/,are strongly reinforced.

Connected with and extending downwardly from the rear tp/p. bar 21, approximately in alinementfavi'th the yokes A, A, are yokes B which have been shown as being constructed of /fbent metal bars, said yokes being reinforced by obliquely disposed braces 32. The bridge piece 33 of each yoke B is provided with hangers 34 supporting a transversely slidable cross bnr 35. .These hangers, as will be best seen by reference to Fig. 6, are provided with downwardly extending arms 36 connected by bolts 37 on which anti-friction sleeves 38 are mounted to support the cross bar 35 which will thus be enabled to move transversely of the machine without undue friction. The lower `ends of the side members of the yokes A atthe front part of the machine are connected with the upper ends of the side members of the yokes B or the points adjacent thereto by means of obliq uely disposed brace bars 39, and similar obliquely disposed brace bars 40 extend from the upper ends of the side members of the yokes A to the lower ends of the side members of the yokes B, said yokes being thereby strongly reinforced against movement of their lower ends longitudinally of the mnchine.

Each pair of yokes A, B serves to.su port a complete working seed drill whi( a includes in its construction a pair of beams or longitudinal frame bars 41 which are equipped at their forward ends with clips 42, best seen in Fig. 7, said clips einbracing and slidably engaging the cross bar or bridge piece 30 of the yoke A; the rear ends of the beams 41 are rigidly connected with and are spaced apart by the cross bar 35 which slides' in the hangers 34. It follows that the beams 35 and all parts connected therewith are capable of sliding transversely with respect to the supporting yokes A, B. For the purpose of effecting transverse movement of the respective drill frames comprising the beams or side members 41 and the cross bars 35 mechanism is provided as follows:

Mounted upon and securely connected with the bridge piecev 30 of the yoke A is a clamp member C, best seen in Fig. 5, said and a bottom member il connected together' and with the bridge memberBOy by means of a bolt 45. The forward part of the clamp member C, in front of the bridge member 30, constitutes a box or bearing for the lower end of a vertical shaft AL6 which car ries a fork 47 wherein a ground wheel L18 is supported for rotation, as clearly seenin Fig. 3; a bearing 49 for the upper end of the shaft 46 is mounted on the front side of the frame beam 20. and said shaft L16 is provided at its upper end with a set collar 50, whereby it is retained in its bearings. The ground wheel 4S thus constitutes a cas ter which will readily adapt itself to the direction of draft. The rearward part of the -clamp C, in rear of the bridge member 30,

lo sprocket wheels 57 are mounted on the shafts 52 at or near the upper ends offsaid shafts. A chain 58 is guided over the sprocket wheels 57 and over the intermediate sprocket wheel 56,' the leads of said chain being maintained in constant engagement with said intermediate sprocket wheel by means of clamp members -D which are mounted on brackets 59 that are bolted or otherwise secured on the frame bar 20, as 2o best seen in Fig. 8; each of said clamp members comprising a pair of clips 60 of substantially U-shape having overlapping limbs 61, the opposed faces of which are grooved or corrugated, as seen at 62; said limbs being also provided with., slots 63 for the passage of connecting bolts 64, whereby said clips'may be adjustably connected'so as to place the leads of the chain under a sufficient degree of tension to maintain said leads securely in engagement with the 'sprocket The shaft 55 that carries the Wheel 56. sprocket wheel 56 also carries a bevel gear 65 meshing with a bevel pinion 66 on a short shaft 67' supported for rotation in the bracket 5,4, said shaft being connected by a universal joint 68 with the forward end of an inclined shaft 69, the rear end of which is supported for rotation on a bracket 70 rising from the frame bar 22. The shaft 69 has a hand wheel 71 whereby it may be rotated by the driver or operator whose seat 72 is supported on a spring bar 73 rising from the frame bar 22. The beams or frame f bars 41 of each drill frame are connected together near their front ends by means of a exible member, such as a chain 74, which e be unwound and the other end of such chain to be wound about the shaft, and therebyl causing movement ofthe frame beams 41 to the right or to the left, according to the direction" of rotation and according to the direction in which the chains 74 are wound about the respective shafts, it being evident 60 that under the arrangement set forth the two shafts 52 will be rotated in one and the same direction. The winding of the chains 74 should, therefore, be reversely about the two shafts, as best seen in Fig. 2, in order that by the rotation of the hand wheel 71, the

a hand lever 78 which is positioned in con- .Now, it will be seen that by adjustment of two framesl each including a ipair of beams 41 may be moved in the direction of each other or away from each other at the will of the operator, thereby enabling the said 'drill frames to be variously spaced apartl 70 in order to secure the best results. This operation, itwill be seen, may be readily performed by the operator while the machine is in motion, and the operator will thus be enabled to control the positions of the drill gangs according to the immediate needs rising from inequalities in the corn rows between which seed is being drilled.

A brace member has been shown as being connected with the bracket 54 and also with. the frame bar 20, said brace member serving in a mea-sure'to protect the chain 58. and related parts from interference. A 'i Supported for rotation' in bearings 76 in. the frame bars 23 and extending across the center bar 22 is a rock shaft 77 which is preferably square or non-circular in cross section throughout the major portion of its length, said rock shaft being provided with vement proximity to the drivers seat and which is equipped with a conventional stop member 79 engaging a segment rack 80 that is supported in the center bar 22 of the frame. Mounted loosely on the rock shaft 77 is a bell crank E having an upwardly extending arm 81 which constitutes a hand lever that is equipped with a Vconventional stop member 82 engaging a segment rack 83 which is fixed on the rock shaft; the other arm of the bell'fcrank E extends 'forwardly, as shown at 84, see Fig. 1, and constitutes a mate to an armor crank 84 thatis mounted securely on the rock shaft 77 from which it extends forwardly, see Figs. 1 and 2. The beams or frame bars 41 of ,each drill frame are provided with brackets 85 supporting. a rock shaft 86 having a forwardly extending arm, the arm associated with one drill frame being designated by 87, and, that associated with the other drill frame being designated by 87', see Fig. 1. The arms 87, 87 are connected by link rods 88 with vthe respective arms 84, 84.

lie

the bell crank E, the arm 84 may be actuated and adjusted at various angles with respect to the arm 84', thereby actuating .the'arm 87 and moving said arm to various positions with respect to the arm 87 thus 120 enabling the said arms 87 and 87 which are associated with the two drill gangs to be variously positioned with respect to one an; other. When such adjustment has been made by` means of the bell crank E, any oscillatory motion imparted to the rock shaft 77 by the hand ilever 78 will be responded to equally by the arms 87 and 87 as will be readily understood, and theparts controlled by said arms, as Will be hereinafter de- 130 ing is also provided with an upwardly extending tubular duct in whichtelescopes the seed duet or spout 96 that extends downwardly from the seed box or hopper 97 which 'is mounted on the beams or frame 41, said hopper containing the customary or conventional drill mechanism whichis actuated by a shaft 98 thatderives motion through the medium of a chain 99'from a source of power which will be presently described. been shown as carrying live furrow opening disks which may be faced, as shown, two in one direction and three in another direction. The two outermost disk casings G associated with each drill frame are provided each a rearwardly extending pivoted lug 100 having a longitudinal slot 101 to receive a crank 102 formed at the lower end of the rods 91 are equippedwith set collars 103 between `which and the cross bar 90 sprino's 104 are'coiled about said rods. The ro s are slidable through the apertures in the cross bar 90 above which each rod is provided with a key or pin 105 whereby the arts are assembled. It will be understood rrom the foregoing description that when the rock shaft 86 is oscillated in one direction to move the furrow opening disks will be raised from the ground, while oscillation of the rock shaft in the opposite direction will cause the cross bar 90 to bear downwardly against the springs 104, which latter will thus tend to force thedisks into the ground. Al1 the .disk casings G are similarly connected with thebar 90, but only the two outermost disk casings are provided with the lug 100 and related parts. l

Each drill frame, comprising a cross bar 35 and side members 41, is provided at the rear ends of said side members with downwardly extending arms or brackets 106 serving to support a shaft 107 on which presser wheels 108 are mounted, said presser wheels being connected with the shaft by means including conventional clutch devices. indicated in Fig. 10 at 109, whereby when the machine is traveling in a. forward direction. the shaft 107 will be rotated with the wheels. The shaft or axle 107 carries a sprocket wheel 110 over which the chain 99 is guided so as to transmit motion to the Each drill frame hasv arms 89 upwardly, the

presser shaft 98 in the seed box. The side bars 41 of the drill frame are also provided at their rear ends with keepers .111 in each of which is mounted a yoke 112, the arms of which are apertured for the passage of a vertical rod 113 carrying at its lower end a presser wheel 114, said presser wheel being forced downwardly by a spring 115 coiled about the rod 113 between the yoke 112 `and a set collar 116 on said rod,-said set collarl being adjustable in order that the tension of the spring may be regulated. A pin or key 117 passing through the upper end of the rody 113 serves to assai-able it with the yoke 112. Braces 118 serve to connect the arms or brackets 106 with the frame members 4.1.

The beams or frame members 41 are provided near their forward ends with downwardly extending brackets 119 reinforced by braces 120 and serving to support a shaft 121 on which plates A 123 are mounted, said plates being connected with the disk carrying casings G except the two outermost ones by means of draw bars 124. This connection permits the disk carrying casings to be moved freely up and down by the hereinbefore described means provided for the purpose, and at the same time, a strong connection is afforded be- 1sk carrying casings.

The shaft 121 is provided adjacent to the ends thereof with U-shapcd supporting members or stirrups 125 on each of which is pir-- oted a pair of arms 126, 127, said arms extending rearwardly, as clearly seen in Fig. 10, and the inner arms 126 being provided. with forward extensions 128 which are connected together by a tension spring 129. The rear ends of the arms 126, 127 are connected together by a spacing member 130, whereby said arms will be maintained in substantially parallel relation; the rear ends of said arms are also connected with the front ends of a pair of links 131` 132 which are connected together by a spacing member 133. The links 131 at the two sides of the frame extend rearwardly and are eonneeted with the disk casings G of the outermost disks; the rear ends of the links 132 are connected by auxiliary links 134 with the forward ends of draw bars 135, the rear cnds of which are connected with plates or blocks 136 mounted on the spindles 137 on which the outermost presser wheels 114 are supported for rotation, said spindles being y formed or attached to the lower ends of the spring actuated supporting rods 113.

It being understood that the drill of theI improved machine are to operate in the interspaces between corn rows, and it being well understood that the rows are invariably ridged up toward the plants, the necessity will readily become apparent for mounting the outermost furrow opening devices 122 having ears or. lugstween the cross bar or shaft 121 and ther rod' 91 associated therewith. The several' d' tessere disks and the outermost presser wheels independently of th'e remaining ones and especially in such a manner as to be capable of moving vertically and also laterally independent of the remaining ones. Freedom of vertical movementis necessary because the said outermost furrow opening devices and presser wheels will be compelled tov travel on the ridges and, therefore, at a greater elevation than tlieiemaining ones, and the freedom of lateral movement is necessary because at times the said outer lmost furrow openers and presser wheels will be crowded in an inward direction, and it is desirable that they should be capable of yielding to such crowding to save the parts from undue strain. Now, it will be observed,that by the action of the spring 129, the rear ends ofthe pivotally supported spaced parallel arms will be forced out* wardly, thereby moving in an outward direction the supporting members of the outermost furrow openers and presser wheels, said furrow openers and presser wheels being, therefore, imbued with the tendency to travel on the respective ridges. When, owing to the irregularities in the surface or from other causes,the outermost furrow i openers'and presser wheels are crowded inward, the said furrow openers and presser wheels will be 4maintained in their normal positions longitudinally, that is to say, the pitch ofy thef'furrow opening diskwill not be changed,andxthe presser wheel will be maintained in a straight position with its am's at right angles tothe line of travel;

` this being due to the herein described arrangement of connecting and supporting members including the cranks `102 and 112.

-Mounted centrally on the front top bar 20 is a socket 138 for the reception of a ball member 1391 at the rear' end of thetongue 140 which extends forwardly, and which carries at its forward end anarched neck yoke 141.l This tongue and neck yoke are obviously 'used only when the machine lis used for drilling in a corn field; for open eld work it is replaced by an ordinary tongue having hounds which may be connected with lugs 142 that extend forwardly from the clip member C. For corn field work,`the draft is applied by means of flexible members, such as chains or cables, for the guidance of which 'pulleys 143 are suitably arranged in various locations on the frame structure; anrevener is provided comprising a frame 144 which is slidably mounted upon a bracket 145 on the rearv frame` applied that foun horses walking abreast.

may be hitched tothe machine, the horses walking in the interspaces where seed is be ingdrlle l' and also in the interspaces adjacent thereto, thus permitting the four horses to walk abreast in the corn field without in'uring thefcorn.

rom the fregoing description, taken in connection with the drawings hereto anneXed, the operation and advantages of this invention will be readily understood. It is obvious that seed drilling mechanism of any conventional and well'lmown character may be used, the main purposes of this invention beingrto provide a frame structure, furrow openers and presser wheels that will lend themselves with particular readiness to the planting of fall crops in the corn fields where the corn has already attained con siderable maturity, as is frequently required in the great corn growing States. The machine is obviously supported in transit,

partly on the front wheels 48 and partly on the presser wheels; and by the simple' mechanism provided the furrow openers of fof suche-nature that the furrow openers of the two drilling devices'may .be simultaneeusly adjusted without being set at various elevations. The general construction of the machine is simple and inexpensive, and it will be found thoroughly efficient for the purposes for which it is provided.

` In the appended claims, for convenience, the drill devices will be referred to as drill units; it being understood that each drill unit includes a pair of frame beams 41, a rear bar 35 and the hopper, furrow openers, presser wheels and other related parts carried by such frame structure.
